About Airprotek International, Inc.
Airprotek International, Inc. is a distributor of a unique line of safety jackets and vests that utilize proprietary air bag technology designed to reduce the risk of injury to motorcyclists and equestrian riders in the event of a collision or a fall.
All Airprotek jackets and vests incorporate the Hit-Air personal airbag safety system designed to reduce the risk of injury to the rider's neck, spine and vital organs in the event of a fall or collision.
In the event of an accident and a rider is thrown from the motorcycle or horse, the air cushion instantly inflates (within 1/2 second) to reduce the risk of injury to the rider's body. Activation is simple and automatic. A coiled wire is attached from the jacket/vest to the motorcycle or saddle. Once the rider separates, the coiled wire pulls a "key" out of a gas release system and inert gas inflates the air cushion to provide the necessary impact protection. Seconds later the gas is automatically released through the gas release valve. Then, a new cartridge can be installed and the jacket is ready for reuse.
